Solidago caesia

Bluestem Goldenrod is a Wildlflower in the Asteraceae family. It is an herbaceous perennial that grows 3 feet tall with showy clusters of yellow flowers that hug greenish-purple stems in the summer and early fall. In recent times goldenrods have been blamed for hay fever, but its irritating symptoms are actually caused by ragweed (Ambrosia species), whose pollen is airborn when goldenrod is in flower. This speices does not spread as rapidly or agressively as some other goldenrods. Works well planted in a native garden, cottage, butterfly, or woodland garden.
